Damage caused by <i>Lophodermium</i> needle cast in open-pollinated and control-crossed progeny trials of Scots pine (<i>Pinus sylvestris</i> L.)
Bibliographic record
Abstract
The effect of genetics on the level of damage caused by Lophodermium needle cast to Scots pine was assessed in an openpollinated progeny trial (226 families from 12 provenances) and in a control-crossed progeny trial (72 families obtained by diallel crossing of 10 parent trees). Each of the trials was replicated on two test sites. The damage caused by the pathogen was estimated visually in June of the 2nd and 6th growing seasons using a five grade scale. Location and genetics were found to be significantly related to the level of needle cast damage. The proportion of severely damaged trees in each family correlated significantly between locations; moreover, the correlation was tighter for the control-crossed than open-pollinated families (r = 0.59 and r = 0.36, respectively), indicating higher stability of resistance level against the disease for the genetically more homogeneous material. The effect of plus tree selection on the proportion of severely damaged trees was similar, regardless of its status (i.e., mother-tree or father-tree) in the family. The progenies of plus trees selected for resin production had the same level of damage by Lophodermium spp. needle cast as the selections made for growth and stem form.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
